Task 5.2: Checkpointing Services

Brief definition of GCA

Set of services and interfaces allowing the legacy and future low-level checkpointing packages to be employed in Grid environment.



The presentation "Towards Grid Checkpoint Architecture" published at PPAM 2005 Conference.

CoreGRID Technical Report Scalable multilevel checkpointing for distributed applications - on the integration possibility of TCKPT and psncLibCkpt [TR-0019; Mar 30, 2006; Gracjan Jankowski, Radoslaw Januszewski, Rafal Mikolajczak - PSNC, Jozsef Kovacs - MTA SZTAKI].

The demo "Reliability in Production Grid Environments Achieved by Multi-level Checkpointing" published at CoreGRID Industrial Conference 2006

Grid Checkpointing Architecture – prototype


  1. When we achieve the final version of definition of the GCA, we plan to begin the work on providing prototype implementation of that architecture (but it is not planned to be done within the period of time encompassed by Roadmap
  2. The most probable development environment:
    • Globus Toolkit 4.0.1
    • Alternatively some other WSRF-based tools


GCA versus GridCPR


  1. GCA is about utilizing a large variety of existing and future checkpointing packages within the Grid environment.
  2. GridCPR defines API and a set of rules that programmers have to adhere to in order to make the new written application checkpointable in the Grid environment. The assumption is that the checkpointing functionality is embedded into the application on the development stage.
